Be it known that I, Anrrrun HAMMOND S IIPLEY, subject of the King of Great Britam, residing at Leicester, in the county of ing' to Brush-Making Machines, of which the following .is a specification, reference being had therein to the accompanying drawing, and for which I have applied for Lat ters Patent of Great Britain, May .21, 1917 which application has matured into British Patent No. 115,890, of May 21, 1917.

, This invention relates to brush-making machines and concerns more particularly though not necessarily exclusively, machines for drilling or boring brush heads,-backs, or stocks. Theinvention is applicable to brush-drilling machines of the class where the stock is carried bya work-holder arranged in a rocking frame combined with said frame is movable upon a horizontal axis and vertical axis whereby the work may. be tilted and turned to obtain the desired bodily movement relatively towards .and from the drill for the necessary drilling motion. Y

The present invention comprises an improvement in the mounting means of the rocking frame whereby it maybe manipulated-more easily for the purpose of drilling L brushstocks and the adjustments necessary for alteringthe angles of the spread of the holes may be more readily made. I

According to this invention the vertical pivotal axis, upon which theframe carrying the work-holder andtemplet turns, is arranged upon a carriage fitted with wheels, rollers I or. other anti-friction devices by which it may travel to and fro along a track in line with the drill. The track is formed in oron a plate movable to different positions along the bed ofthe machine and adapted, to befastened therein "by'a bolt or other suitable means.

It is also a feature ;of the invention that the horizontal axis upon which the work Figure 1.

The

rocking frame is also efl'ectedin a similarmanner by means of rack rods and. gears.

In particularly describing. the invention reference will be hereinafter-made to the accompanying drawings wherein a concrete vform of the. improvements constituting an example of the invention, is shown applied to a machine for drilling or boring brush heads or stocks. i v

In the drawings referred to Figure 1 is a side elevation of the machine Figure2is a plan of the same. F gure 3 is a vertical section of the riage and its car bed taken .on the line a,@ of

supporting means of the rack rods at the horizontal axis of. the rocking frame.

Figures 4, 5and 6 are drawn to a larger scale than Figures 1, 2 and 3, and'throughout the drawings like. parts are designated; v v by the sameureference characters. I spread of the holes, and it is also capable of Referringto Figures 1 and 2, the brush drilling machine to which the present imdrill'spindle 4 the pulley 5 thereon being driven by a belt 6 from the pulley on the driving shaft 8. The drill-spindle is fitted with a chuck 9 to hold the drill (not shown) which passes throughv a gauge 10 secured I i e i sectional detail view ofa fasupon one of the bearings 3 this member bei ing adjustable to different positions in rear of the point of the drill-and serving to deter minev the depth of thevholes formed in the stock.

The work carrying frame comprises generally, transverse rods 11 (Figure 2), rack rods 12, an axis bar 13, rack rods 14, and a turnable bearing plate 15.

The transverse rods 11 are: provided thereon with workholding devices 16 of suitable form for supporting the brush head or stock these devicesbeing adjustable along said rods to difsuit the size, of the 1 work 'ferent positions to to be held.

: Combined with the work carryingfranie and really forming part of same is 'a templet 17 carried by side rods18 which are rigid with h a P sa l templet constitut 19 ing the means bywhich the operator manipulates the whole work carrying frame by hand for drilling the stock. The frontportion of the work carrying frame constituted by the parts 11, 12, 17 and lS-is movable up and down uponhorizontal axes 19 (Figures 1, 5 and 6) these being formed upon opposite ends of the axis bar 13. The whole work carrying frame is movable horizontally upon a vertical axis 20 Figures 1 and 2, which axis is arranged as will presently be described, to be capableof bodily movement in a direction longitudinally of the machine. The rising andfalling fore part of the work carrying frame is held up and balanced by cords 21 (Figure 1') which pass Over Pu l y (not shown) and have a weight conibine'dtherewith in such a manner that free movement of the frame is permitted. It will be understood that the frame being movable vertically on'the axes 19, horizontally on the axis 20,and longitudinally, the work can be moved about and brought into Contact with'the rotating drill, the position of the holes to be drilled in the stock being determined by pattern holes in the templet 17 which are employed'in conjunction with a stationary point 22 (Figures 1 and 2) carried in a standard 23fastened upon the bed 1.

According to "the present invention the vertical axis20 upon'which' the work carrying frame turns horizontally is arranged upon a carriageyor trolley 24 (Figures 1, 2

and 3) which, in the embodiment shown,

is mounted upon two wheels 25 arranged to run tandem fashion along a V track 26 formed. on a plate 27 movable to different positions along the machine bed 1, said plate bolt and nut 28. I

The carriage or trolley 24 is balanced and kept upright by a wheel or roller 29 oneach '27 being fastened onthe bed by means of a side thereof (Figures and 3) and running 1 in contact with the underside of a fixed rail 30 attached to supports 31 on the plate 27.

1The'wheels or rollers 29 are mounted upon 7 an axle 32 (Figures3 and 4) they ends 33 of ,which are eccentric to the centre part The wheels are rotatable upon the ends'33, and thecentre part- 32 passes through bearin'g'bos'ses 34 on the carriage 24 and is nor- 'mally fastened therein but may be rotated thefa'pplication of a spanner to the squared extremity35 for the purpose of setting the whee ls up tothe rails 30 to take up wear. The axle 32 may be fastened in the bearing bosses 34, by means of a clamp bolt device combined "with one of said bosses. This is illustrated in Figure 4 which shows said boss in vertical section. The boss lhasa lug 36 formed upon one side thereof [furnished with a hole, disposed at right angles to the axle 32 in which hole, there is arranged a clamp bolt 37 having upon it a 42'by tightening nuts47.

sleeve 38. The adjacent'ends of the sleeve 38 and bolt head 39 between which there is a "space are cut away at one side for the axle 32 to pass between them as shown, and when the nut40 on the bolt is tightened the sleeve is forced along the bolt and the axle is firmly clamped in the boss 34 by the wedging action of the sleeve and bolt head thereon. v

The carriage or trolley 24 arranged in the manner described gives ease of movement when manipulating the work carrying'frame to bring the stock into and out of engage ment with the drill. This easymovementis permitted by'the wheels 25 runningto and fro along their tracks .26, the plate 27 being of course previously positioned on the bed 1 to suit the range of movementof the carriage.

The vertical axis 20 consists of a pin firmly secured in a boss'ed lug 41 on the bearing plate 15(Figure 1) said pinfitting and rotating within suitablebearingholes in the carriage or trolley 24. By prefere-nce ball direction may be obtained.

The adjustment of the rods 14 through the bearings 42 is brought about in the embodiment shown by means of'gear wheels 43 on a spindle 44 rotatable by a handwheel 45 in bearings 46 onthe bearing plate 15, said gear wheels meshing with rack teeth formed upon theunderside of therods 14. Byrotating the hand wheel 45 in one direction or the other the rods 14 on opposite sides of the bearing plate 15 are simultaneously advanced or retracted as may be're quired and after adjustment in'thismanner said rods may be fastened in their bearings As previously stated, the axes 19 upon which the fore part of the work carrying frame may be raised and loweredto tiltthe stock and thereby obtainthespread ofthe holes in a vertical direction, are formed upon the opposite ends of the bar l3which 1s attached to the rods 14. To carry the rack rods 12 the said axes 19 eachhavemovably arranged'thereon a mounting 48 "(Figures 1, 2, 5 andG) the'boss 49 of which is free to turn on the axi's'pin 19 [while through a bearing 50 the rod 12 is adapted to slide.

To facilitate the adjustment of the saidrods 12 through their bearings 5 whereby the position of the templet 17 and work holding devices 16 relatively to the horizontal axes is changed to vary the angle of vertical spread of the holes to be drilled, said rods have rack teeth 51 (Figure 2) formed on the top side thereof with which gear wheels 52 (Figures 1, 2 and 6) engage. These gear wheels are fast upon a transverse shaft 53 carried in bearings 54 on the mountings 48 and when rotated by means of a hand wheel 55 move both the rods 12 through the mountings to effect the desired adjustment of the parts previously mentioned. The bearing 50 is slotted at 56 (Figure 5) to expose the rod and allow the gear wheel 52 to engage with the teeth 51.

The rods 12 are fastenedin position in the bearings 50 after adjustment preferably by the same form of means as that previously referred to for securing the axle 32 such means consisting of a clamp bolt 57 ure 6), sleeve 58 and nut 59, said bolt and sleeve being located in a-lug 60 (Figure 5) on the mounting 48. Similar fastening means may be used in the bearings 42 for fastening the rods '14:.

By means of the gear wheels 43 and 52' and their co-operating rack teeth on the rods 14 and 12, the adjustable parts of the work carrying frame may be easily moved to any means tohold said carriage down on the track, a plate supporting said track, and a.

bed, said plate being movable to different positions on the bed for the purpose de scribed.
